The only thing you can do is lower the ground level from the wall, and help water away from the edges.

There is a drainage coil you can get which looks like a pill (vertical and narrow with curved ends). There is also a type of concrete sealer you can get to paint the concrete so it resists water from being absorbed. Use that, put the draianage coil against it and help the water want to leave.

Would this work? https://www.bunnings.co.nz/reln-stretch-drainage-pipe-socked-slotted-16m_p00315166

And is there any tips to install? Do I need any specific ends for the drainage pipe?

I had a similar problem. You dig a trench along the wall, maybe 10 - 20cm wide and 20 - 30cm deep. You put draining dock in the bottom say 5cm, then drainage coil, then some more rock, then cover it with soil and replace the grass. The drainage coil obviously has to drain somewhere. This works well.

I also waterproofed a brick wall with this clear commercial grade sealer I got. I could look in the shed and see what it's called. It was $150 for about 10L, I have plenty left, if you're in Wellington and it's still ok I'd sell it for not a lot. I doubt it would help this situation though.

Awesome thanks Mate, I'll go into bunnins and grab some pipe. Was there a specific amount of drop per meter you did for laying the pipe?

Thanks for the offer of the sealer but dunno if it would work on cement board.

Nah. Water flows downhill - a plumber told me if you can remember that, you can be a plumber :) Just trying and get a bit of fall on it, even 5-10cm across a shed I reckon would be fine. I used something like this, but mine didn't stretch, it was what it was. It's basically a semi flexible pipe with holes in it with a sock over the top.

Bunnings will probably sell drainage chip as well, if not Google it for your city. Something like this.

The cement board should be well clear of ground level. You may have had dirt washing down against your garage wall. While you are digging a drain get the ground level along the wall below the bottom timber plate.

Was thinking this:https://www.geofabrics.co/products/megaflo

It’s on the kapiti expressway apparently.

For the edges look here:http://www.safeguardeurope.com/applications/floor-slabs-new

Or failing that a mulseal of some sort - basically a tar/pitch barrier for the concrete in the ground to resist water, combined with the coil to take water away. Tar eventually breaks down, but anything has to be better than nothing.
